What is SPDIF in audio?

S/PDIF (Sony/Philips Digital Interface) is an audio transfer format interface. It transfers digital audio signals from one device to another without the need to first convert to an analog signal, which can degrade audio quality.

Which connectors are used for digital SPDIF audio?

The most common connector used for S/PDIF is an RCA coaxial connector. While S/PDIF RCA coaxial uses the same connector as the analog RCA connection on consumer audio products, the cables are not the same, and these connections should not be confused.

Is the SPDIF cable the same as the ground loop?

S/PDIF refers to the signalling, not the conductor type. Fiber has the advantage of never causing a ground loop, which can have odd effects in digital, which may or may not be audible as a traditional ground loop. Some swear that copper sounds better, which could have something to do with the connector hardware/drivers.

Can a coax cable be used to connect a PDIF transmitter?

Technically speaking, any wire can be used to connect an S/PDIF source to a S/PDIF target/receiver. However, COAX cables are mostly recommended because of their shielding (which is critical on a S/PDIF cable) and the ability to try to adhere to the 75 ohm requirement for S/PDIF transmitter/receiver specification.

Is the SPDIF XLR cable the same as the RCA cable?

If the AES3 XLR cable can be connected to RCA with a simple adapter it is SPDIF which is really now considered a variant of AES3 if you need an impedance converter for it to work it is AES3 type 1 or the old AES/EBU standard. AES3 is used in professional installations with XLR 110 Ohm balanced or BNC 75 Ohm unbalanced.
